To all whom t may concern.'

Be it' known that I, EMANU'L J. BOYLER, a citizen of the UnitedStates, residing at New Haven, inthe county of New Haven and State of Connecticut, have invented vnew and useful Improvements Ain Separable Fasteners, ofwhich the following isa specication.

This invention relates `to improvements Iin separable fasteners; and-more particularly to a fastener of thejhead and'socketf type.

`It is the obj ect of'this invention to provide a separable fastener vin which the-head `is engaged by a resilient wire -in the socket, from which the head may be readily disengaged.

The advantages of this invention arethe simplicity of construction and the small number of parts which cheapen the cost 01E assembling, land the thinness' off the united parts of the'fastener when engaged which is'ext'remely desirable as these 4fasteners 'are used extensively on ladies dresses. n

W-hile the preferred forms of this inv'env tion are illustrated upon the accompanying sheets of drawing yet it; isy to be understood that minordetail changes may be made with out :departing from the scope thereof.

Fig. l2 vis Aa transverse sectionalV view, taken.` on the line 12-12, Fig. 11,'0 -the complete fastener.

In' carryingtout this invention,`the fastener includes ahead member comprising a disk'l ofrlightmetal having head2 struck up centrally thereon, with a restricted neck portion 3,.and a socket member comprising a circular 'base plate t *ofy light metal having a central'opening 5` ofsuiiicient size for vthe head 2 to pass therethrough, and a circulartop plate Giof'light metal secured upon the base plate byspinning aflange 7 from the base plate thereon,fwitha centrally struck "circular protuberancel 8 adapted to ,cover theihea'd when in place. Both the head and lsocket'members are prof vided with a plurality oi aperturesy 9 for sewing or otherwise attaching the parts to the dress goodsror material carrying thefastener. f

Between thetop and'. base plates of the socket vmember a spring head engaging means isinOunt'ed s0 .thatV when. the headis vvforced home itiwill expand the spring which `rwi'll Athereafter contract about the restricted neck of the head and hold the parts together against side strains `but release the:` parts n vVon'e arm'lo'ngerthan the other andsecu'red its end opposite its base between the top and base plates under the base ange and with its shorter arm free to move. Upon insertion of the head the longer arm being secured at each end, leXes slightly at the center, while the shorter arm being free at one end iieXes at its base, allowing the head to enter and the shorter armsnaps back to normalagainst the restricted neck 3 of the head and holds the opposite sides of the neck against the other arm of the spring.

Figs. 8 and 9 illustrate another form in which the spring securing `means comprise a wire spring 11 bent in the form of a semicircle with the ends bent straight in the same plane to lie parallel and on each side of the head receiving aperture 5. The curved portion is secured between the top and base plates under the base flange with the end of the outer straight portionl likewise secured while' the inner straight portion is shorter and free, the normal distance between the straight portions being substantially the diameterf of therestricted neck 3 of the head 2. The action of the spring in this case is substantially the same as when the U-shaped spring is employed, the diierence being larger anchorage therefor effected .by the semi-circularportion being secured under the base flange.

Another form or modicaton is shown on Figs. 9 and 10, in which the head securing means comprise a wire spring 13 bent centrally upon itself with the bend secured between the top and base plates under the base'flange. The portions of the spring extend therefrom at a slight angle to each other and areeach curved about the head receiving aperture 5 upon the arc of a circle, the distance between the opposite points of the arc being normally equal to the'diameter of the restricted neck of the head. The ends of the spring are similarly curved'back upon their respective bodies free of the securing base flange 7 and their extremities curved outward substantially in line with .each other and the edge of the head receiving member and are secured between the top and base plates under the base flange. In this form, when the head is 'forced home, the central bend being secured, the bodies on each side flex between the bend 4and the secured ends,

and the-curved portions between the arcs and bends impart greater resiliency to the spring.

Figsll andl?J illustrate another form or modification in which the Spring securing means comprises a, rectangular plate llt' of light spring metal having a central aperture 15 registering withl the head receiving aperture of the base pla-te and its endsy secured between the top and base plates under the base flange. A section of the plate 16 on each side of the central aperture 15 is bent upward and outward therefrom, then bent back and downward upon itself until the distance between the 'sections 16 equals'substantially the diameter of the restricted neck 3 of the head 2'. The sections may be terminated here, but it is preferable to bend each one upward and back upon itself, as illustrated on Fig. 12. When the head is forced home the spring sections 16 are forced apart but will contract and engage the restricted neck to hold the parts together.

In all forms the complete fastener is' extremely Hat being but little thickerthan the height of the head member and this Vis made possible by the simple construction `as abovedescribed. With the exception of the spring all parts are struck `from sheet metaland the assembling of the socket is very simple as there areonlythree parts l,to be put together and the spring is held betweenv the .top and base plates by s inning or crimping the flange from the ase plate about the top plate. -vThere are no parts to become disengaged in the socket and the spring, upon whichetheoperation of fastener depends, is completely covered and protected.

What I claim is :---4 v l ,A separable fastener including a head member comprising a base plate; a head thereon, provided with arestricted; neck portion; a socket member including a base plate provided with an opening through which the head is insertible; a top plate securedat its outer edgesl to the base plate, and having ya raised portion to cover the head when insertedgpsaid top plate beingfinspaced relation to the baseplate inthe regionof the, opening,.to constitute a housing; and a spring member having a body portion secured between, the edges of thetop and base plates, and having arms extending inapproximate parallelism on either side of; the opening, said arms having one end free, andadapted to engage the neck portion when the head is inserted through the opening.
